I have to agree with Setec that you used too much product. A 10 ml syringe is enough for an SUV. You should not have to wipe "excess" but going back over is to ensure even distribution. You can vary the thickness and certainly add a second layer, but they only guarantee coverage and don't affect durability. Brad, lot's of first timers use too much product thinking it's like waxing and more is better. And it is hard to see, a penalty of going on perfectly clear. There is no rule concerning when to level because that's determined by thickness of product and atmospheric conditions (hot/humid cures more quickly than cool/dry). In good light you can see Gloss-coat flash, a rainbow effect, and that's when you gently wipe down. The applicator is reusable, just rinse out in hot water/dish detergent.
